Forum email notifications and how to stop them! 

I joined the forum months ago because I was facing an issue with Zuki (that I eventually solved by buying a later version).
Since then, I started receiving daily notifications of every post and comment that I could not sign out for. I went through the unsubscribe procedure, but the emails keep coming and spamming my work mailbox.
I emailed Ellen, asking to manually remove my address a few weeks back, but it didn’t work either.
Did anybody else face the same issue?

This is getting extremely annoying. The emails I receive from this forum (also related to themes which aren’t mine) outnumber the messages I receive for work. I don’t want to receive any notifications!

Please help!
